A Continental-scale Seismic Observatory

Central and Eastern United States Seismic Network (CEUSN)

Recent earthquakes in the CEUS, including the 2011 M5.8 Virginia earthquake, have raised awareness of the comparative lack of knowledge about seismicity, site response to ground shaking, and the basic geologic underpinnings in this densely populated region of the country. The mission of the CEUSN is to produce data that enables researchers and Federal agencies alike to better understand the basic geologic questions, background rates of earthquake occurrence and distribution, seismic hazard potential, and associated societal risks of this region.
